The PRISMA 2020 Flow Diagram Generator ("the tool") is built to keep your work private. This page explains exactly what is and is not collected when you use it.

Summary

• Your diagram data is never sent to us or to Google. The review title, numbers, labels and diagrams you enter stay in your browser.
• We use Google Analytics only to measure basic, anonymous visit statistics for the site.
• We have turned off Google Analytics' optional automatic tracking features (listed below).
• The site is supported by advertising served by Google AdSense. Google and its partners may use cookies to show ads (see Advertising below).
• There are no accounts and no sale of data.

What we collect from your diagram

Nothing. The tool has no accounts, no server-side processing and no database. Everything you type into the generator is processed entirely in your browser and is never uploaded.

What is stored on your device

• Autosave: your current diagram inputs are saved in your browser's local storage so you can pick up where you left off.
• Theme preference: your light or dark choice is saved in local storage.
• Saved files: "Save progress" and the PNG, SVG and PDF exports are created on your device and saved wherever you choose.

This data stays on your device. You can remove it at any time with the Reset button or by clearing this site's data in your browser settings.

Cookies and analytics

This site uses Google Analytics (Google tag) to understand how many people visit and which pages they view. Google Analytics uses cookies and collects standard visit information, such as your approximate location (derived from your IP address), device and browser type, the pages you load, and how you arrived at the site. We see this only as aggregated reports.

Tracking features we have turned off

Google Analytics offers optional "enhanced measurement" features. On this site they are all switched off, so the following are not collected:

• Scrolls: we do not record when you scroll to the bottom of a page.
• Outbound clicks: we do not record clicks on links that lead away from this site.
• Site search: we do not record search queries. The site has no search feature.
• Form interactions: we do not record when you interact with a form. The diagram form fields are never sent to Google Analytics.
• Video engagement: we do not record video activity. The site has no embedded videos.
• File downloads: we do not record file downloads, including your PNG, SVG, PDF or saved-progress exports.
• Page changes from browser history: we do not record automatic page-view events triggered by history changes.

Google Analytics still records that a page was loaded, together with the standard visit information described above.

Your choices

You can opt out with the Google Analytics opt-out browser add-on, or by blocking cookies or scripts in your browser or with a tracking-blocking extension. Blocking analytics does not affect how the tool works. See how Google uses information from sites that use its services.

Advertising

The tool is free to use and is supported by advertising. Ads on this site are served by Google AdSense, a service of Google.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• Ad requests include standard information such as your IP address, device and browser type and the page you are viewing. The contents of your diagram are never included, because they never leave your browser.

Your advertising choices

• You can opt out of personalised advertising in Google's Ads Settings.
• You can opt out of personalised advertising from other participating vendors at aboutads.info or, in Europe, youronlinechoices.eu.
• Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for their consent before advertising cookies are used, and can change that choice at any time.
• You can also block or delete cookies in your browser settings. The tool keeps working if you do.

Third-party services

• Google Fonts: the page loads the Geist font from Google Fonts. Your browser therefore sends a request, including your IP address, to Google. See Google's privacy policy.
• Google Analytics: loaded from googletagmanager.com to measure basic site usage, as described above. See Google's privacy policy.
• Google AdSense: serves the ads shown on the site and may set advertising cookies, as described under Advertising above. See Google's privacy policy.
• Website hosting: the site is served by a third-party hosting provider, which may keep standard server logs (such as IP address and browser type).

Children

The tool is intended for researchers, students and faculty and does not knowingly collect information from anyone, including children.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date.
